0.38-2GHz Planar Helical Antenna with SMA-K Connector
ZD-PHA-0.38/2G-ZD03820-0.5B
This ZD03820-0.5B planar helical antenna is a reliable-performance, right-handed circularly polarized antenna designed for indoor and outdoor wireless communication scenarios, including 4G LTE, IoT, and fixed wireless access (FWA) deployments. Its ≥90° beam width (across 380-2000MHz frequency range) ensures effective signal coverage in scenarios such as small-to-medium-sized commercial spaces, industrial workshops, and outdoor equipment monitoring stations. With a standing wave ratio ≤2.5 and back lobe ≤-12dB, it minimizes signal interference and ensures stable signal transmission, enhancing connectivity reliability in complex wireless environments. The antenna features a compact structure with reference dimensions ≤360mm×360mm×250mm and weight ≤2500g, supporting flexible installation (compatible with surfaces matching its 4-ϕ6.20 mounting holes). Crafted with Alufer antenna cavity material and grayish-blue (GY09) pigment, it boasts excellent durability, withstanding extreme temperatures ranging from -40℃ to +55℃ (working) and -50℃ to +65℃ (storage). Ideal for wireless communication systems requiring wide-frequency coverage and circular polarization, this planar helical antenna delivers consistent performance in both indoor and outdoor harsh environments.

The 380-2000MHz Planar Helical Antenna (Model: ZD03820-0.5B) is a reliable-performance, right-handed circularly polarized antenna tailored for versatile wireless communication scenarios, serving as a practical solution for 4G LTE, IoT (Internet of Things), and fixed wireless access (FWA) deployments. As an Indoor & Outdoor Universal Antenna, it adapts to diverse installation environments—from small-to-medium commercial spaces and industrial workshops to outdoor equipment monitoring stations—thanks to its robust operational temperature range of -40℃~+55℃ and storage temperature range of -50℃~+65℃, ensuring stable performance even in extreme weather or harsh industrial conditions.
Constructed as an Alufer Cavity Antenna, this model leverages the durable Alufer material for its antenna cavity, paired with a grayish-blue (GY09) pigment coating, which enhances structural strength and resistance to environmental wear, extending the antenna’s service life. Operating across the wide frequency band of 380MHz~2000MHz, the 380-2000MHz Planar Helical Antenna delivers a gain of ≥-0.5dB, with a beam width of ≥90° (absolute gain better than -4dB for 380~500MHz and -2dB for 500~2000MHz), ensuring effective signal coverage and transmission stability. Key performance metrics further validate its reliability: a standing wave ratio (VSWR) of ≤2.5 minimizes signal reflection, a back lobe of ≤-12dB reduces interference from unwanted directions, and an SMA-K type stainless steel connector guarantees secure, low-loss signal connectivity.
The 380-2000MHz Planar Helical Antenna features a compact mechanical design, with reference dimensions of ≤360mm×360mm×250mm and a weight of ≤2500g, supporting flexible surface mounting via its 4-ϕ6.20 installation holes—no complex adjustments are needed for setup. As an Indoor & Outdoor Universal Antenna, it bridges the gap between indoor connectivity needs (e.g., IoT device networking in commercial buildings) and outdoor signal coverage requirements (e.g., remote equipment monitoring in industrial yards). The Alufer Cavity Antenna’s rugged build and the 380-2000MHz Planar Helical Antenna’s wideband, circular polarization advantages make it an ideal choice for wireless systems that demand consistent performance, environmental adaptability, and long-term durability, particularly in scenarios where single-channel, reliable signal transmission is a core requirement.
